Abstract

Abstract: To address the complex multiphysics coupling and lack of theoretical guidance for spray parameters in aircraft ground de-icing, a simulation model based on the Phase-Field method and Realizable k-ε turbulence model is proposed to investigate inclined jet flow over airfoil surfaces. The model enables the numerical reconstruction of jet impingement, liquid film flow, and unsteady heat transfer processes, providing a framework to elucidate the regulatory mechanisms of jet angles on momentum distribution and thermal characteristics. The simulation results reveal distinct variations in the flow and heat-transfer characteristics at different jet inclination angles. At a jet angle of 15°, the maximum normal impact pressure is generated, making this condition more suitable for breaking strongly adhered ice. At 45°, the most effective conversion of jet momentum into tangential spreading is achieved, and the highest liquid-film velocity is obtained, thereby providing a favorable balance between impact intensity and de-icing fluid coverage efficiency. Although greater temperature loss in the free-jet region is induced at 60° because of the enhanced entrainment effect, the surface area characterized by high Nusselt numbers is significantly enlarged, making this condition more suitable for maintaining anti-icing fluid coverage after de-icing. The numerical results provide a theoretical basis for the refined optimization of aircraft ground de-icing operations. This research establishes a theoretical foundation for precision aircraft ground de-icing operations.
